WINDMILL.

Specification of Letters Patent.

Patented Oct. 5, 1915.

To all whom it may concern:

Be it known that I, DANIEL R. SC-HOLES, citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Windmills, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

The invention relates to wind mills and has for its objects the simplificationand improvement of wind mill mechanism.

The wind mill of my invention lncludes a wind wheel, a mill vane, a supporting head for said wheel and vane and upon which the vane is mounted to open from and close toward the wheel, a tower terminating at its upper end in an upright tubular column upon which the mill head is mounted to rotate about an upright axis, a coupler disposed about the upright column and movable longitudinally thereof and upon the exterior of the tower structure, this coupler having one member which is rotatable about the column and a second'member also disposed about the column and provided with means for substantially limiting it to movement along the column, motion transmitting means between the first aforesaid coupler member and the vane for effecting movement of-the vane with respect to the wheel, and motion transmittin means intervening between the second aforesaid coupler member and the lower portion of the tower to enable an attendant to operate the vane, the two motion transmitting means being upon the exterior of the column and mill head.

A specific form of the invention, but to which form the invention is not to be limited, is shown by the accompanying drawings in which duced upper end constitutes an upright shaft 3 affording an upright axis about which the wind mill head 4 may turn upon a step bearing ring 5 supported upon the loWer column portion.

Instead of separately forming and thereafter assembling the tubular portions 2, 3, they are integrally made from a single piece of pipe originally of the diameter of the larger part of the column, the shaft 2 being formed by contracting the upper part of the column, while the lower step bearing carrying part retains its original diameter. The shaft 10 of wind wheel 11 is journaled upon the mill head and carries a pair of upright pinions or gears12 for driving the upright pump or load rod 13. A pair of upright transmission gears14 are in mesh with the pinions or gears 12 and are j ournaled within a bearing 15 carried by the head 4. Pitmen 16 connect gears 14 with the upperend of load rod 13. A stirrup 17 is fixed upon the upper end of the load rod and carries a shaft 18. Stirrup19 engages and guides roller 20 on shaft 18. The gears 12 are relatively fixed and, to driving power between the two sets of meshed gears and their pitinen, the gears 14 of the other pair are free to move relatively in their planes to compensate for inaccurate alinement of the teeth of. either or both pairs of gears. Said gears 14 are therefore provided with shafts 21, 22 that are in telescop- 1ng and relatively rotatable relation, the outer sleeve shaft 22 being directly supported by the bearing 15 and itself constituting a bearing for the inner shaft 21 which may also be hollow if desired. Relative end play of the gears 14 is prevented by the inter-engagement of the shafts 21 and 22 shown in Figs. 6 and 7. In the structure of these figures the gear shaft 21 carries an oblong end 21 which may be positioned to slip through an oblong continuation 22 of the bore of shaft 22 whereafter said shafts are relatively rotated to bring the flat end 21 n some such relationship as that illustrated in Fig. 7 and which relationship is substantlally maintained by the intermeshing of gears 14 and gears 12.

The mill vane 24 has a stem 25 mounted upon the head 4 to swing about an upright axis. A coil spring 26 connects the mill vane with the extension 4 of head 4 and, as shown, operates to maintain the vane open and the wheel 11 in the wind. A lever 27 (Fig. 1) may be operated against the force insure the even division of of spring 26 to close the vane toward the wind wheel to bring this wheel out of the wind. Bufier springs 28 and 29 cushion the vane when moved to closed and open posi tions respectively.

The larger portion of the stationary column 2 is encircled by a coupler or cross head 31 to which is attached a non-rotating stirrup or other extension 32 that is connected with the upper end of a wire 33 whose lower end is connected with lever 27. A chain or other suitable form of flexible tic member 34: passes over rollers 35 and is connected at its lower end with the coupler and at its upper end with thevane stem 25. \Vhen the lever 27 is depressed the stirrup 32 and coupler 31 are drawn downwardly to cause the chain 34: to pull the mill vane to a closed position. Any suitable form of braking mechanism may be employed to check the idle rotation of the wind wheel when out of the wind.

To enable the chain or tie 3% to move bodily with the mill head the lower end of said tie is connected with a ring t2 forming a. rotatable part of the coupler. The ring 42 is caused to accompany head 4: in its bodily movement by means of a long finger mill head extension that is in permanent sliding engagement with and between projections 44:, formed upon the ring, irrespective of the vertical position of the ring. A brace 45 connects the lower end of the finger with another portion of the head 4 (Fig. 2).

Claims respecting the telescoping arrangement of the gear wheels and pinions are included in my division of this application Serial No. 865,481t, filed October 7, 191i.

lVhile there is herein shown and particularly described the preferred embodiment oi the invention the invention is not to be limited to the precise details of construction shown as changes may readily be made with out departing from the spirit of the invention, but

Having thus described the invention there is claimed as new the following A wind mill including a wind wheel; a mill head; a supporting tower; and an upright tubular column fixed at the upper end of said tower and having a lower portion upon which the mill head may turn and an upper portion of smaller diameter that con stitutes a shaft about which the mill head may turn, said column portions being integrally formed from a single tube.

In witness whereof, I hereunto subscribe my name this twenty third day of March A. D., 1914.
